dbSNP rs1315065108: CASC3:p.Ser75Trp (chr17-40140772-C-G) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2

The NM_007359.5(CASC3):c.224C>G(p.Ser75Trp) variant causes a missense change. The variant allele was found at a frequency of 0.00000584 in 1,027,596 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S75L) has been classified as Uncertain significance.

Genes affected

CASC3 (HGNC:17040): (CASC3 exon junction complex subunit) The product of this gene is a core component of the exon junction complex (EJC), a protein complex that is deposited on spliced mRNAs at exon-exon junctions and functions in nonsense-mediated mRNA decay (NMD). The encoded protein binds RNA and interacts with two other EJC core components. It is predominantly located in the cytoplasm, but shuttles into the nucleus where it localizes to nuclear speckles.
